When I turn on headlights car dies
I have a 2003 Mazda 5.. When the is running and I turn on the head lights the car dies and it doesn't start back up.
Get the battery and charging system checked, that sounds like a complete charging system failure.
I just put in a new battery and alternator.
That still doesn't mean that it is working, I believe that your charging system is computer controlled on this model, so take it back to the shop that diagnosed the problem and tell then that they didn't fix your problem.
